Question

-(4-k)+3(k-3)= 2) -(3-k)-12(k+12)= 3) -(-p)+4k-2(p-2k)=​

Answer 1

Ответ:

Пошаговое объяснение:

-(4-k)+3(k-3)= -4 + k + 3k - 9 = 4k - 13

2) -(3-k)-12(k+12)= -3 + k - 12k - 144 = -11k - 147

3) -(-p)+4k-2(p-2k)=​ p + 4k - 2p + 4k = -p + 8k

Answer 2

Let's solve each equation step by step:

1. -(4-k) + 3(k-3) = 2

To solve this equation, first distribute the negative sign to both terms inside the parentheses:

-(4 - k) = -4 + k 3(k - 3) = 3k - 9

Now, the equation becomes:

(-4 + k) + (3k - 9) = 2

Combine like terms:

-4 + k + 3k - 9 = 2

Add the constants and combine the 'k' terms:

4k - 13 = 2

Now, isolate 'k' by adding 13 to both sides:

4k = 2 + 13 4k = 15

Finally, divide by 4 to find the value of 'k':

k = 15/4

2. -(3-k) - 12(k+12) = 0

First, distribute the negative sign to both terms inside the parentheses:

-(3 - k) = -3 + k -12(k + 12) = -12k - 144

Now, the equation becomes:

(-3 + k) - (12k + 144) = 0

Combine like terms:

-3 + k - 12k - 144 = 0

Combine the 'k' terms:

k - 12k = 3 + 144 -11k = 147

Now, isolate 'k' by dividing both sides by -11:

k = 147 / -11

k = -147 / 11

3. -(-p) + 4k - 2(p - 2k) = 0

First, simplify the double negative:

-(-p) = p

Next, distribute the negative sign to the terms inside the parentheses:

-2(p - 2k) = -2p + 4k

Now, the equation becomes:

p + 4k - 2p + 4k = 0

Combine like terms:

p - 2p + 4k + 4k = 0

Combine the 'p' terms and the 'k' terms:

• p + 8k = 0

Now, isolate 'p' by adding 'p' to both sides:

8k = p

Finally, isolate 'p' by dividing both sides by 8:

p = 8k

So the solution to the third equation is p = 8k.
